PMS vs. PMDD - What's the Difference?
Ms. B.T. is 38 years old. Her co-workers always seem to know when she has her period. During this time, she becomes extremely irritable. She feels guilty because she gets very angry at her children for no logical reason or for apparently trivial reasons. In fact, one of her coworkers, with whom she is quite friendly, suggested she come in before her supervisor
noticed problems on the job. She heard that there is a severe version of PMS
that requires special treatment.

What is premenstrual dysphoric disorder (PMDD)?
Premenstrual dysphoric disorder (PMDD) can be considered a severe form of premenstrual syndrome (PMS). Both PMS and PMDD are characterized by unpleasant physical and psychological symptoms that occur in the second half of a woman's menstrual cycle, most commonly in the days preceding the menstrual period. Physical symptoms such as bloating, breast tenderness, headaches, joint pain, food cravings, mood swings or frequent crying, panic attacks, fatigue, mood changes, irritability, and trouble focusing are among the most common symptoms. Other symptoms like anxiety and trouble sleeping have been reported. PMS symptoms may be troubling and unpleasant. PMDD may cause severe, debilitating symptoms that interfere with a woman's ability to function.
The American College of Obstetricians and Gynecologists estimates that at least 85 percent of menstruating women have at least one PMS symptom as part of their monthly cycle. PMS is much more common than PMDD. You must have 5 or more of the symptoms listed above to be diagnosed with PMDD.
Biologic, psychological, environmental, and social factors all seem to play a part in PMDD. It is important to note that PMDD is not the fault of the woman suffering from it or the result of a "weak" or unstable personality. It is also not something that is "all in the woman's head." Rather, PMDD is a medical illness that impacts only 3% to 8% of women. Fortunately, it can be treated by a health care professional with behavioral and pharmaceutical options.
PMDD has been previously medically referred to as late luteal phase dysphoric disorder.
